Abstract :
We demonstrate a compact in-fiber low-resolution spectrometer. Wavelength resolution of 7 nm was achieved using the core radiation-mode coupling of a tilted grating in an optical fiber with a photosensitive cladding. We applied the device to measure the powers of a multiwavelength Raman pump source.
